Kristen Stewart flew across the country to attend the New Jersey wedding of her friend, Hollywood producer Kevin Turen, this Saturday. Her mistake? Forgetting to pack a dress, People reported.

Stewart quickly borrowed a short navy Zac Posen dress from the groom’s sister, which matched her Louboutins, People reported. Apparently the memory lapse only extended to articles of clothing intended to cover the body, not the feet.

But for reasons open to speculation — comfort? style? — Stewart was back to wearing jeans by cocktail hour. She did combine them with a smart blazer, but underneath wore a black tank top sheer enough to show her bra.

After the wedding, which Stewart attended in coupley fashion with Robert Pattinson, Stewart flew to Paris for a shoot, according to the Daily Mail.
